1) Refactor nod_value_if.
...
2) Created ExprNode::expressionEqual method to replace a new big and ugly switch.
3) Make boolean referencers use BoolExprNode instead of jrd_nod, except nod_validate for now. This includes BinaryBoolNode and NotBoolNode working without jrd_nod references.
4) Rework in the impure allocation code (replace "csb_impure += ..." by CMP_impure calls).

1) Simplify the explicit plan handling between the parser and the engine. It makes no sense to pass the join type as it's ignored internally.

2) Support hash joins in the plan output and in the parser. For the latter, it's just the syntax sugar, same as loop vs merge join (see above).
